We use win32gui to enumerate all windows, get their pid to check and then append the hwnd to the list.

def get_hwnds_for_pid (pid): def callback (hwnd, hwnds): _, found_pid = win32process.GetWindowThreadProcessId (hwnd) if found_pid == pid: hwnds.append (hwnd) return True hwnds = [] win32gui.EnumWindows (callback, hwnds) return hwnds hwnds = get_hwnds_for_pid(3196) print hwnds
